Question

Prove that the each example below is a Pythagorean triple Sides are 279,440,521

Answer 1

Explanation:

a^2 +b^2 =c^2

279^2 +440^2=521^2

77841 + 193600= 271441

271441= 271441

(I used the pythagorean theorem formula. I knew 521 was c because c is the hypotenuse, which is the longest side. The other two sides are interchangable.)

Hopefully this helps!
